FIELD OF THE INVENTION

The present invention pertains to a fruit-based snack and a method of a manufacturing such a product that contains only natural ingredients and does not contain sugars or corn syrup, and has various desirable other characteristics as described below.

BACKGROUND OF THE INVENTION

Confectionery items such as licorice, jelly beans, and sugared jellies made with sugar, water, and food starches have been popular for decades. These confections have a firm, yet pliable texture which contributes to their desirable eating quality. These confections are typically manufactured by a starch mold casting process known as the Mogul system. In this process, the liquid ingredient blends consisting of sugar, corn syrup, food starch and other food ingredients are heat processed at a temperature above the boiling point of the liquid mixture until a moisture level above that of the finished confection is reached and the starch is fully gelatinized. In a typical production process of a commercial Mogul system, the ingredients are heat processed at a moisture level of about 20 to 25 weight percent at a temperature of about 250° to 350° F. for less than 1 minute. The starch is generally an acid-thinned (also known as thin-boiling) commercial corn starch or a high-amylose starch or a blend thereof. After heat processing, the hot liquid mixture is deposited into a starch mold. The starch mold defines the shape of the confection and helps to reduce the moisture content. The deposited confections are then routinely dried for about 24 to 72 hours to reach the desired moisture content of about 14 to 20 weight percent.

Confections called fruit snacks that are produced by the above process and include a certain percentage of fruit juices and fruit purees have become very popular with consumers because of their healthy connotation. The heat processed fruit snack mixture must set quickly in the starch molds in order to avoid molding starch getting imbedded in the deposited pieces. Thin boiling starch along with sugar and corn syrup in the formulation functions as a quick setting agent. Some starch in the fruit snack formulation can be replaced with gelatin. Replacing all the starch produces a tough gummy bear or wine gum type texture and is not desirable. Sugar and corn syrup are also essential ingredients in the process. A significant reduction in the sugar and corn syrup content of the formulation gives a sticky/tacky surface that is difficult to manage on packaging equipment. The sticky/tacky texture is also not desirable from a consumer appeal point of view. For the foregoing reasons, it is has not been heretofore possible to produce a good quality fruit snack produced from fruit juices and purees without the use of acid thinned starches alone or in combination with gelatin.

OBJECTS AND SUMMARY OF THE INVENTION

In view of the foregoing, it is an object of the present invention to provide a formulation for a fruit based snack, and a manufacturing method thereof, that maintains all the desirable characteristics of such types of products, including a chewy soft texture, without the use of sugars and corn syrups.

It is a further object of the present invention to provide a fruit-based snack that includes only fruit-based products as sweetening agents.

It is another object of the present invention to produce a fruit-based snack that contains only natural ingredients.

It is yet a further object of the present invention to provide a fruit-based snack that can be produced by traditional manufacturing processes, such as starch molding.

It is yet another object of the present invention to provide a formulation of a fruit-based product that maintains an excellent eating quality, has an extended shelf life, and maintains the other desirable eating characteristics, while retaining healthy nutrients.

To achieve the foregoing and other objects, a fruit snack of the present invention is manufactured, in summary, by providing fruit juice concentrate having a moisture content of substantially 15% to 20%, mixing the fruit juice concentrate with fruit purees, mixing the fruit juice concentrate with a gelling agent, and depositing the fruit juice concentrate with the fruit purees and the gelling agent in a Mogul machine to produce the fruit snack product.

As an aspect of the present invention, the process may entail providing fruit juice concentrate having substantially a 30% moisture content, heating the provided fruit juice concentrate to a temperature of substantially between 250 to 300 degrees Fahrenheit for a predetermined period of time, and then vacuuming excess moisture from the heated fruit juice concentrate to produce fruit juice concentrate having substantially a 15% to 20% moisture content.

As another aspect of the present invention, the gelling agent is a combination of gelatin and pectin.

As a feature of this aspect, both the gelatin and pectin are used as texturing agents. As another feature, the gelatin comprises 1 part gelatin and two parts water.

As a further aspect of the present invention, the produced fruit snack product has a translucent appearance.

As an additional aspect of the present invention, natural colors and flavors are added during manufacturing of the fruit snack product.

As yet another aspect of the present invention, the produced fruit snack product is cured for substantially 24 hours.

As yet a further aspect of the present invention, the fruit juice is pineapple juice concentrated to substantially 80 Brix.

As yet an additional aspect of the present invention, the fruit purees include apple puree.

As yet another aspect of the present invention, the fruit snack product does not include added sugars or corn syrups.

In accordance with the present invention, a fruit snack product produced by a starch molding process, comprises fruit juices, fruit purees and other sweetening agents derived from fruits, flavoring agents, stabilizers, acidulants, fruit flavorings, and coloring agents.

As an aspect of this inventive fruit snack product, the sweetening agents are derived only from fruit-derived ingredients.

As another aspect of this fruit snack product, pectins and gelatin are used as texturizing agents.

As a further aspect of this fruit snack product, the product includes only natural colors and flavors.

Various other objects, advantages and features of the present invention will become readily apparent to those of ordinary skill in the art from the following detailed description of the invention.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

Currently, it is generally believed in the industry that it is impossible to produce an acceptable fruit snack using only natural ingredients and without the use of acid-thinned starches. Modified starches can't be used because they are chemically modified and are not considered natural. Using gelatin as the texturing agent produces an undesirable very tough, gummy-type texture, as illustrated in examples 6 and 7 discussed below. Reducing the amount of gelatin in the formulation unacceptably results in products not setting properly and, moreover, provides a thick crust of starch after the products are cured. Other natural texturing agents similarly do not produce an acceptable all-natural fruit snack. For example, using pectin as the texturing agent, as illustrated in examples 5 and 8 below, resulted in the product setting-up too quickly in the depositing hopper. In addition, the final product did not set-up properly and was covered with starch.

Despite the current beliefs and the dissatisfactory results achieved with various formulations, such as illustrated in Examples 2 through 8 below, the fruit snack of the present invention is all-natural, has an excellent, chewy soft texture, and does not contain sugars or corn syrups. The fruit snack of the present invention includes only fruit-based products as sweetening agents, has an extended shelf life and other desirable characteristics mentioned herein. As described in further detail below, the fruit snack of the present invention may be manufactured using traditional manufacturing processes.

A fruit snack having the foregoing attributes is manufactured in accordance with the present invention in multiple steps, as herein described. Initially, fruit juice concentrate having a 15 to 20% moisture content is provided. Such fruit juice concentrate may be obtained by using commercially available juice concentrates, which generally contain about 30% moisture, and removing some of the moisture. Typically, the commercially available fruit juice concentrate is heated to about 250 to 300 degrees Fahrenheit for a short time and excess moisture is vacuumed off to produce the concentrate with 15 to 20% moisture content.

The reduced moisture content juice concentrate then is mixed with fruit purees and further is mixed, in accordance with the present invention, with gelling agents comprised of a combination of gelatin and pectin. In the exemplary formulation shown in Example 1 below, by using both gelatin and pectin as the texturing agents, the heat-processed mass did not set-up in the depositing hoppers and the finished product had an excellent texture and eating quality and, further, the produced fruit snack pieces were not covered with starch residue. Still further, the resulting product had a highly desirable translucent appearance.

The cooked mass, which contains the reduced moisture content juice concentrate, fruit purees, gelatin and pectin, is deposited on a Mogul machine to produce the final product. Since the design and operation of a Mogul machine is well known to a person of ordinary skill in the art, a detailed description of a Mogul machine, including the different designs and operations thereof, is not provided herein.

Natural colors and flavors preferably are added to the processed mass on a continuous basis. The product then is cured for a set period of time, e.g., 24 hours.

EXAMPLE 1

In this Example 1, the fruit snack in accordance with the present invention was manufactured using the ingredients shown in Table 1 below. Initially, the pineapple juice concentrate was further concentrated to about 80 Brix. Apple puree and pectin then were thoroughly mixed in with the pineapple juice concentrate.

A gelatin solution consisting of 1 part gelatin and two parts water was homogeneously mixed into the mixture, which then is further processed to a Brix of 77 at 190 degrees Fahrenheit using heat and vacuum evaporation. Natural colors and flavors were added to the processed mass on a continuous basis and deposited in starch molds with cavities of about 1.5 CC volume by pumping the cooked mass to a starch molding machine.

After a 24-hour curing period, the product was judged to be highly acceptable for taste, flavor, texture and appearance.

As described above, the formulation of the fruit snack of the present invention includes both gelatin and pectin, which unexpectedly advantageously increased the setting time of the heat processed mass, thus making it possible to deposit the product in starch molds. Moreover, although the product had a very low viscosity at the depositing stage, the liquid molten mass unexpectedly advantageously did not attract the starch, and the product set-up cleanly.

Accordingly, the snack product of the present invention manufactured as herein described has the above-mentioned advantageous features and characteristics, including being all-natural, having a chewy soft texture, having only fruit-based products as the sweetening agents, does not include sugars or corn syrups, has an extended shelf life, and is capable of being manufactured using traditional manufacturing processes.

By way of comparison, fruit snacks were also created in the manners set forth in Examples 2-8 discussed below.

EXAMPLE 2

Using the ingredients shown in Table 2 below, pineapple juice concentrate of about 72 Brix was concentrated further to about 80 Brix under heat and vacuum. Apple puree concentrate of about 30 Brix was thoroughly mixed with the pineapple juice concentrate and processed to a temperature of 190 F. and 77 Brix. The cooked mass was pumped to a starch molding machine while continuously injecting acids consisting of vitamin C and citric acid, and colors and flavors and deposited in cavities of about 1.5 CC volume. The product was allowed to set for 24 hours at 65 degrees F. The product was discarded because it did not set and was inedible. The fruit snack pieces also showed a large amount of imbedded starch in them.

EXAMPLE 3

Using the ingredients shown in Table 3 below, white grape juice concentrate was further concentrated to about 80 Brix, as in Example 2. Apple puree and carrageenan gum were thoroughly mixed in the white grape juice concentrate using a high speed mixer for complete dispersion. The batch was then further processed as in Example 2 and the concentrated mass was deposited in starch molds at about 190 degrees F. The batch was discarded because it set very quickly in the depositing hoppers and the piping and could not be molded satisfactorily.

EXAMPLE 4

A batch was prepared as in Example 2, but processed and deposited to a final temperature of 220 degrees F. The product could not be molded satisfactorily. It also produced a pronounced burnt flavor.

EXAMPLE 5

Using the ingredients shown in Table 5 below, apple juice concentrate was further concentrated to about 80 Brix, as in Example 2. Apple puree and pectin powder were thoroughly mixed with the concentrated apple juice with a high speed mixer and further processed as in Example 2. After a 24-hour setting/curing period, the product showed uneven set and had a large amount of imbedded starch. The eating quality of the product was unsatisfactory.

EXAMPLE 6

Using the ingredients shown in Table 6 below, pineapple juice concentrate was further concentrated to about 80 Brix. Apple puree and a gelatin solution consisting of 2 parts water and one part gelatin were thoroughly mixed with the pineapple juice concentrate and heat processed under vacuum to 77 Brix and 190 degrees F. The batch was further processed as in Example 2. After a 24-hour curing period, the product was tested for overall eating quality. While the product showed excellent appearance and desirable aroma, it was quite tough and more like a gummy bear than a fruit snack.

EXAMPLE 7

Using the ingredients shown in Table 7 below, a production batch was processed as in Example 6. The only difference between the batches was the amount of gelatin (as well as the amount of juice and puree concentrate). After a 24-hour curing period, the product was judged to be unacceptable because of a large amount of imbedded starch in the pieces.

EXAMPLE 8

Using the ingredients shown in Table 8 below, apple juice concentrate was further concentrated to about 80 Brix as in Example 2. Apple puree and pectin powder were thoroughly mixed with the concentrated apple juice with a high speed mixer and further processed as in Example 2. The cooked mass could not be satisfactorily deposited in the starch molds because it setup too fast. After a 24 hour curing period, the product showed a tough set. The eating quality of the product was unsatisfactory.
